求翻译：目前, 主要由直接合成法以对苯二甲酸和异辛醇（2-乙基己醇）,在催化剂作用下合成DOTP。随所用催化剂的不同, 酯化反应所表现出的反应行为和规律也各有差异。是什么意思？

At present, mainly by direct synthesis of terephthalic acid and ethylhexanol (2 - ethylhexyl alcohol) in the catalyst synthesis dotp. Demonstrated with different catalysts used in the esterification reaction behavior and the laws vary.

At present, mainly by direct synthesis methods in order to direct 2 formic acid and ethylene glycol (2- of ethyl alcohol), and in the catalyst role DOTP combined. With the use of catalyst, the reaction of methyl ester demonstrated a reaction and also have different laws.

At present, mainly by the direct synthesis by the dicarboxylic acid and the different propyl butyl-carbinol (2- ethylhexanol), synthesizes DOTP under the catalyst function.Along with uses the catalyst the difference, the esterification to respond displays the response behavior and the rule also resp

At present, mainly by the direct synthesis of ISO-Octyl alcohol and Terephthalic acid (2-ethyl alcohol), DOTP synthesis catalyst. Used with different catalysts, esterification reaction the reaction behavior and rules vary.
